4.2 DC Electrical Characteristics

Table 4-2. Operating Frequency VS. Voltage
Param. No. VDDIO, VDDANA Range Temp. Range (in °C) Max. MCU Frequency Comments
DC_5 1.9V to 3.6V -40°C to +85°C 64 MHz Industrial
Note:
  1. The same voltage must be applied to VDDIN and VDDANA.
  2. MLDO mode (Linear regulator): 1.9V - 3.6V

    DC-DC mode (Buck regulator): 2.4V - 3.6V
